"We were at a meeting actually," a Medway resident said. "All of a sudden we heard a big loud explosion. I didn’t know what it was at first. But it was loud enough that we all stopped."

Several people reported feeling the shaking from Millis to Medway to Franklin and Framingham.

Most people told NewsCenter 5 that they were unsure what was happening.

"I was just sitting on my couch watching TV, and I did feel something.," another Medway resident said. "It is an old house and I thought maybe the furnace started or something, but I got a text and someone said, 'Did you hear about the earthquake?'"
